78 HYMENOPTEEA. 



ocelli and apex of the clypeus, rather long, subclavate ; all the joints (but especially 

 the basal one) of the flagellum longer than broad ; basal joint thick, shorter than the 

 third ; the third joint a little longer than the fourth. Head nearly as wide as the 

 thorax, alutaceous, above covered closely with a fuscous pubescence ; the clypeus and 

 cheeks with short silvery hair ; eyes converging towards the mouth ; a narrow furrow 

 runs down from the ocelli ; clypeus broadly but not largely convex, the apex depressed, 

 slightly waved. Thorax : the mesonotum alutaceous ; the pleurae shining, impunctate ; 

 mesopleural keel fine, but distinct. Median segment with the area distinct ; a wide 

 furrow running down the centre, and from the side of the base a crenulated furrow 

 runs obliquely to the middle, joining the median furrow near its centre; the segment 

 itself has a gradual rounded slope ; the metapleura has the furrow deep and covered 

 rather densely with white hair. Abdomen as long as the head and thorax united ; the 

 petiole becomes gradually widened from the base to the apex, and is about three fourths 

 of the length of the second segment ; the second segment is very gradually and not 

 greatly widened towards the apex, and is very shining, impunctate ; the other segments 

 are opaque, very closely covered with a fuscous pubescence. The mesopleural furrow 

 is nearly complete ; the tubercles and a small spot behind them are red ; the median 

 segment has a small red spot in the centre ; the inner orbits of the eyes are red in the 

 middle ; the tibiae are reddish-yellow in front ; the basal joint of the middle tarsi is 

 yellow in front ; the fore tarsi are obscure red at the apices of the joints ; the depression 

 at the front of the scutellum is finely foveolate or rather crenulate ; the petiole is 

 broadly black at the apex and along the sides, and has a squarish mark in the centre at 

 the base ; the other segments are banded with red ; the apical segment black, pilose, 

 impunctate. The second cubital cellule is about half the length of the third at the top, 

 and longer than the space bounded by the recurrent nervures ; the cost a is obscure 

 testaceous, bounded with black ; cubitus faint, but distinct beyond the third cellule.

Antennae subclavate; the third joint a little longer than the first, and nearly one 

 quarter longer than the fourth ; joints 3-6 longer than broad, 7-11 broader than long, 

 4-6 and part of 3 dull rufous beneath. Eyes slightly but distinctly converging towards 

 the clypeus ; hinder ocelli separated from each other by a somewhat greater distance 

 than they are from the eyes. Front and vertex slightly convex, shagreened, and bearing 

 scattered, moderately large punctures. Frontal furrow narrow, shallow. Clypeus
